The silver moonlight filtered through the heavy velvet curtains, casting long and jagged shadows across the cold marble floor tiles. Detective Miller stepped over the yellow tape, his breath hitching slightly as he surveyed the gruesome scene before his eyes. A single crystal glass lay shattered near the hand of the victim, its contents staining the floor a dark crimson. The grandfather clock chimed midnight with a somber tone that seemed to echo through the empty and silent mansion corridors. No one heard the scream that surely preceded this tragic end, leaving the investigator with nothing but haunting, quiet questions.
